KITCHEN-RANGE FIRE BLOWER AND SOOT CLEANER.

Application filed February 1, 1924. Serial No. 690,084.

To all whom t may concern.'

Be it known that I, RILEY CULenn'rsoN, a citizen of the United States,residing at Glezen, in the county of Pike and State of Indiana, haveinvented certain new and useful Improvements in Kitchen-Range FireBlowers and Scot Cleaners; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in kitchen ranges and it is myprincipal object to provide novel means whereby a draft of air may beforced upwardly through the grate to quickly kindle a tire or to producemore rapid burning after kindling, and whereby any soot accumulating inthe ovenheating flue, may be readily blown therefrom.

With the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, the description beingsupplemented by the accompanying drawings.

Figure 1 is substantially a central vertical longitudinal sectionthrough a kitchen range embodying my invention.

Figure 2 is a rear elevation showing more particularly the arrangementof the fan for producing the blasts of air.

Figures 3 and 4 are sectional views as indicated by lines 3--3 and %4 ofFig. 1.

In the drawings above briefly described, the numeral 1 designates akitchen range having a grate 2, an oven 3, a direct draft flue 4 fromthe tire box to the usual smoke outlet opening 5, and an oven-heatingflue which extends downwardly at 6 behind the oven 8, then extendsforwardly as at 7 under said oven and finally leads upwardly as'indicated at 8, to communicate with the opening 5. I have shown adamper 9 at the inlet end of the flue 6-7-8, for controlling the passageof smoke therethrough, and have illustrated another damper 10 at theoutlet 11 of the line 4 and it will be seen that by properly regulatingthese dampers, the smoke from the fire may pass through the direct draftflue 4, or may be shunted around the oven to heat the latter.

The back wall 12 of the range 1 is formed with an opening 18 into theportion 6 of the oven-heating Hue and is formed with another opening 14into the ash pit below the grate 2. A circular fan casing 15 is securedagainst the outer side of the wall 12 and is provided with an airdischarge nipple 16 passing snugly through the opening 18 and isalsoyprovided with a. similar nipple 1T extending through the opening14. 'The two nipples 16 and 17 are of tubular form and in them, I mountpivoted damper plates 18 and 18a respectively, said plates havingoperating rods 19 and 19rL which extend to the exterior of the casing15, so that either of said damper plates may be opened.

Under the grate 2, I provide a perforated tube 20 having a closed end 21and an open end which is snugly engaged with the nipple 17, so that anyair entering said tube through said nipple will be upwardly supplied anddistributed through the grate 2, to promote. rapid burning of the fire.

Within the casing 15, is a rotary fan 22 driven by speed gearing 23 anda crank 24, said gearing being located in a suitable gear casing 25secured to the outer side of said casing 15. This last named casing maybe secured to the range in any suitable manner, but I prefer to provideit with a continuous fiange 26 through which bolts or rivets 27 pass,these fasteners being also passed through the wall 12.

By properly setting the dainpers 9 and 10, closing the damper plate 18aand opening the plate 18, an air blast will be directed through thenipple 16 when the fan 22 is rotated, and this blast will effectivelyclean the flue 6-7-8, of any accumulated soot and the like. IVhen thedamper plate 18 is closed and the plate 18a is opened, rotation of thefan will supply a forced draft to the fire to facilitate kindling orburning after the kindling operation.

I prefer to embody my improvements in connection with a range of thetype shown, but it is obvious that they may be used in connection withother forms of stoves.

I claim:

A kitchen range having an oven, a grate, and a damper-controlled iiuefor heating said oven, said range having an opening in one wall undersaid grate and another opened in said nipples for controlling thedischarge of ail1 therefrom, and operating rods for said damper platesextending to the eX- teiioi' of said fan casing.

In testimony whereof I have hereunto afv fixed iny signature.
